Major projects

• TORO Clock A clock based on an 8-bit CPLD-implemented custom CPU

Quick hacks

• Tek PS-2521G Maintenance
• Not-So-Cordless Drill Tired of repacking NiCd/NiMH packs? Use a gel-cell lead-acid battery!

Software

• FreeBSD stuff
• FileFormatConverters.exe for Office 2003. Needed to read new DOCX, XLSX, etc. formats.

Information

• Metcal MX-500P technical documentation, reverse-engineered by -unknown-. Includes schematic, and may be applicable to the PS2E-01.

• Web page #2 with tear-down pictures.
• Fluke 8840A Service Manual (includes schematics)
• LeCroy LA313/LA314H Serice Manual (includes schematics) -- appears that Iwatsu SS-7840/SS-7847 are clones of this design, but no guarantees!
• 1988 Cypress CMOS Data Book Contains data and programming algorithms for PALC22V10
• MC88110 User's Manual (MC88110UM/AD) Rare documentation for this obscure, short-lived architecture
